hbase 结点之间时间不一致造成regionserver启动失败

  http://sishuok.com/forum/blogPost/list/5411.html

Caused by: org.apache.hadoop.ipc.RemoteException: org.apache.hadoop.hbase.ClockOutOfSyncException: Server s3,60020,1304927875246 has been rejected; Reported time is too far out of sync with master.  Time difference of 41450ms > max allowed of 30000ms

1.方案1
在hbase-site.xml添加配置
<property>
        <name>hbase.master.maxclockskew</name>
        <value>180000</value>
        <description>Time difference of regionserver from master</description>
 </property>

2.方案2
修改各结点时间，使其误差在30s内

我写了一个同步时间的shell脚本

 

 

#!/bin/bash
echo "start"
for ((i=211;i<=218;i++))
do

#ssh 192.168.5.${i} 'date 110415402010; clock -w'
ssh 192.168.5.$i 'date -s "2011-05-10 10:44:00"; clock -w'
#ssh 192.168.210.${machine} 'clock -w'
done
echo "complete"
